Hi Sattar,
Thanks for using Syncfusion product.
We can navigates to specified destination within the document by using DocumentLinkAnnotation.
Kindly use the below code to add annotations,
// Drawing Annotation
RectangleF docLinkAnnotationRectangle = new RectangleF(110, 130, 93, 65);
PdfDocumentLinkAnnotation documentAnnotation = new PdfDocumentLinkAnnotation(docLinkAnnotationRectangle);
documentAnnotation.Text = "Document link annotation";
documentAnnotation.Color = new PdfColor(Color.Navy);
documentAnnotation.Border.Width = 3;
documentAnnotation.Border.HorizontalRadius = 25;
documentAnnotation.AnnotationFlags = PdfAnnotationFlags.NoRotate;
PdfPage page2 = document.Pages.Add();
documentAnnotation.Destination = new PdfDestination(page2);
documentAnnotation.Destination.Location = new Point(10, 0);
page.Annotations.Add(documentAnnotation);
page.Graphics.DrawString("Click on the rectangle to move to next page", font, PdfBrushes.Black, new PointF(100, 240));
Please look into the sample which is available in the below specified location and let me know if this helps.
